I find it less compelling to jailbreak. When I switch from one provider to another it usually takes the form of contract and right now a provider like AT&T or T-Mobile gives good deal on phones. I am actually less and less on phone spec. My Atrix used to be a top phone on spec but after using it for 6, 7 months I notice it being slower and slower. And then you can't upgrade to latest Android because officially Motoral doesn't support it and I don't want to deal with custom upgrade (I have done too many and many just fail my phone). I used to get expensive unlocked phones myself but now I can get a good deal from contract bundle and they offer quite a good range of selections.

After two years I am still using this old Atrix. I might switch to Nexus one day if I had the budget for it. iPhone isn't my cake so I'd passed on. But I have to praise a closed system like iOS - update is great. No fragmentation.
